We've been talking about the good life, and what gets in the way. Today we hear the invitation into it. If someone invited you to make your life better, would you take it? What would you pay? What would you sacrifice? How much effort, vulnerability, and humility would you give - for meaning, for joy, for peace?

In the earliest Gospel, Jesus' first words announce that God's kingdom has come near, and He calls people to repent and believe the good news. "The time has come," he said. "The kingdom of God has come near. Repent and believe the good news!"

in the beginning, a good God made a good creation and walked with His people in it - life as it was designed to be. - The goal was never simply heaven someday. Scripture ends with a new creation. - When Jesus was among sinners and outcasts, you could see the kingdom: everyone fed and taken care of, the sick healed, the peace and presence of God, power to overcome evil.

- Matthew 13:44: finding the kingdom is like finding treasure hidden in a field - a discovery so valuable you'd gladly give everything to have it. - 1 Corinthians 15:20: Jesus' resurrection is the firstfruits of the new creation - proof God can remake anything. He took the worst thing that ever happened and turned it into the best thing that ever happened. - The kingdom is an invitation into the life you were made for: a life of being healed, walking with God, at peace - shalom.

- That's the announcement. Then comes the invitation to respond: repent and believe the good news. This is where we focus today. - "Repent" in Hebrew (shuv) means turn around, return: realizing you're walking down a road of self-destruction, and turning back to God and His way. - "Repent" in Greek (metanoia) means a total transformation of your mind, posture, and perspective: rethinking your whole life, your whole strategy for living, your fundamental framework of reality and success - a return to your original vocation as an image bearer. - "Believe" means allegiance and trust. It's not mere mental agreement - there is movement involved. - Repent and believe are two sides of the same coin: you can't just do one. Turn from, and turn to. Without repentance, the throne is still occupied - you're just adding Jesus. Without belief, you're turning with nothing to turn to - and that ends in despair. - Acts 2:38: at Pentecost, the crowds respond to the good news by repenting and being baptized. Acts 19:19: believers in Ephesus show their belief by repenting in action, burning their sorcery scrolls.

- Repentance is not confession. It's not just acknowledging the broken part, where you're missing the mark. It's rethinking - digging down to find the root belief, the root lie - and deciding to turn from that. - And this should bring you joy, because you're turning from death to life. Acts 3:19: repent and turn to God, and times of refreshing will come from the Lord. - Repentance is an ongoing thing. Martin Luther's first thesis: Jesus willed the entire life of believers to be one of repentance - not a one-time doorway into Christianity, but the primary engine of ongoing spiritual growth.

- This is hard, because things are entrenched, and we don't want the walk of shame. So we delay. We bargain. - Luke 14:15-24: in Jesus' parable, the invited guests excuse themselves - a field to see, five yoke of oxen to try out, a marriage to attend to - while the host fills his banquet with the poor, the crippled, the blind, and the lame. There was still room, but the invited never tasted the feast. - Saint Gregory warned that the Evil One bargains for our delay: "Give me the present, and God the future; give me your youth, and God your old age" - cheating us by little procrastinations. The busiest day on the calendar for repenting is tomorrow.

- Luke 15:7, 10: there is more rejoicing in heaven over one sinner who repents than over ninety-nine who need no repentance. Luke 15:17: the prodigal son's whole story turns when he "came to his senses" - it starts with a thought.
